Pregnant & two year old is driving me crazy

I am 7weeks & 4 days & my two year old daughter is driving me insane ! I do not want to imagine when i get bigger ... she cries for every little thing always wants to be carried by ME , her dad offers to carry here & she doesn’t want him. All of a sudden she forgot how to get inside the car & sit in her car seat , now I have to be carrying her & putting her because she won’t do it herself. She’s always wanting my attention & cries for it... I guess it’s because im pregnant because she’s never been this way.. what can I do to calm her down ?
